  1. DIRECT COMPUTATION OF TURBULENCE NOISE

    SBC: Aerochem Research            Topic: N/A

    N/A

    SBIR Phase I 1988 National Aeronautics and Space Administration
  2. EXPERT SYSTEM FOR FINITE ELEMENT MODELING

    SBC: Autodesk Inc.            Topic: N/A

    MOST TYPICAL PROBLEMS IN STRUCTURAL ENGINEERING ARE BEST ANALYZED BY APPROXIMATING AN OBJECT'S GEOMETRY WITH FINITE ELEMENTS. SELECTING AN APPROPRIATE MESHING STRATEGY FOR A GIVEN SOLID REQUIRES KNOWLEDGE ABOUT FINITE ELEMENT THEORY IN GENERAL, AND ABOUT PACKAGE-SPECIFIC DETAILS IN PARTICULAR. THE ADEPT SYSTEM INTEGRATES A TRADITIONAL SOLIDMODELER WITH AN EXPERT SYSTEM EQUIPPED WITH THIS KNOWLEDGE ...

  3. TACTILE TELEPRESENCE SYSTEM FOR DEXTEROUS TELEROBOTICS

    SBC: Begej Corp.            Topic: N/A

    THE OBJECTIVE OF THIS PROJECT IS TO DESIGN AND FABRICATE AN INNOVATIVE FINGERTIP-SHAPED TACTILE TELEPRESENCE SYSTEM FOR DEXTEROUS TELEROBOTIC SYSTEMS. THE PRINCIPAL TASKS TO BE PERFORMED ARE: (1) DESIGN OF VARIOUS MINIATURE TACTILE STIMULATOR ELEMENTS AND EVALUATION OF THE ACTUATION STRENGTH, DISPLACEMENT MAGNITUDE, FREQUENCY RESPONSE RANGE, AND THERMAL LOADING CHARACTERISTICS, (2) CONSTRUCTION OF ...

  4. ASYNCHRONOUS MULTILEVEL ADAPTIVE METHODS FOR PARTIAL DIFFERENTIAL EQUATIONS ON THE NAVIER-STOKES COMPUTER

    SBC: Colorado Research Development            Topic: N/A

    NASA IS CURRENTLY SUPPORTING A VERY PROMISING PROJECT FOR DEVELOPMENT OF A HIGH-POWERED MULTIPROCESSOR SYSTEM, THE NAVIER-STOKES COMPUTER (NSC). WHILE MULTILEVEL ALGORITHMS ARE BEING STUDIED IN THE NSC ENVIRONMENT FOR SOLVING THE ELLIPTIC EQUATIONS THAT ARISE IN DISCRETIZING INCOMPRESSIBLENAVIER-STOKES EQUATIONS, NO RESEARCH HAS YET FOCUSED ON LOCAL ADAPTIVE SCHEMES FOR THIS PURPOSE. THIS IS IMPOR ...

  5. SYMBOLIC IMAGERY MANAGEMENT SYSTEM (SIMS)

    SBC: Command Control, Inc.            Topic: N/A

    THE USE OF IMAGERY FOR THE PRESENTATION OF DATA IS BECOMING INCREASINGLY COMMON. INTEGRATING IMAGE DATA WITH GRAPHIC DATA STRUCTURES AND FEATURE INFORMATION IS VERY DIFFICULT USING TRADITIONAL DIGITAL REPRESENTATIONS. SEPARATE IMAGE AND FEATURE INFORMATION DATABASES ARE COMMONLY USED, BUT THE ANALYST IS REQUIRED TO MAINTAIN TWO OR MORE DATABASES AND TO PERFORM INTEGRATION OF THE INFORMATION IN HIS ...

  6. ROTOR UNSTEADY AIRLOADS

    SBC: Continuum Dynamics Inc            Topic: N/A

    OVER THE PAST SEVERAL YEARS, UNDER GOVERNMENT AND COMMERCIALSUPPORT, CONTINUUM DYNAMICS, INC. HAS MADE SIGNIFICANT PROGRESS IN COMPUTING THE UNSTEADY WAKES OF FIXED- AND ROTARY-WING AIRCRAFT. THIS PROGRESS, FOR THE MOST PART, RESULTED FROM THE SUCCESSFUL DEVELOPMENT OF THE BASIC CURVEDVORTEX ELEMENT AS A FUNDAMENTAL WAKE ELEMENT BUILDING BLOCK AND A NOVEL GENERALIZED VORTICITY CONTOUR REPRESENTATI ...

    SBIR Phase II 1988 National Aeronautics and Space Administration
  7. ANALYSIS OF MAIN-ROTOR-WAKE/TAIL-ROTOR INTERACTION NOISE

    SBC: Continuum Dynamics Inc            Topic: N/A

    THE IMPORTANCE OF REDUCING THE NOISE OF THE HELICOPTER TAIL ROTOR HAS BEEN RECOGNIZED FOR MANY YEARS. HOWEVER, BOTH THE PREDICTION OF TAIL-ROTOR NOISE AND THE DEVELOPMENT OF LOW NOISE DESIGNS HAS BEEN IMPEDED BY POOR ABILITY TO SIMULATE NOISE-GENERATING INTERACTIONS BETWEEN THE MAIN-ROTOR WAKE AND THE TAIL ROTOR. IN MANY CASES, EVEN THEFLIGHT CONDITIONS LEADING TO SUBSTANTIAL MAIN-ROTOR/TAIL-ROTOR ...

  8. PERFORMANCE OPTIMIZATION FOR ROTORS IN HOVER AND AXIAL FLIGHT

    SBC: Continuum Dynamics Inc            Topic: N/A

    N/A

    SBIR Phase I 1988 National Aeronautics and Space Administration
  9. "DEVELOPMENT OF A UNIQUE LABORATORY STANDARD INDIUM GALLIUM ARSENIDE DETECTOR FOR THE 0.5-1.7 MICRON SPECTRAL RANGE "

    SBC: Eti Instrument Systems Inc.            Topic: N/A

    SPECTRAL MEASUREMENTS OVER THE VISIBLE/NEAR-INFRARED 0.5-1.7 MICRON RANGE CANNOT BE DONE AT PRESENT WITH A SINGLEDETECTOR. TWO SEPARATE DETECTORS (SILICON FOR 0.5-1.1 MICRONS AND GERMANIUM FOR 1.0-1.7 MICRONS) MUST PRESENTLY BE USED IN ORDER TO COVER THE ENTIRE SPECTRAL RANGE. THIS COMPLICATES MEASUREMENT PROCEDURES AND ADDS COST AND EXTRA COMPONENTS TO THE SYSTEM. WE PROPOSE TO DEVELOP A LARGE-AR ...

    SBIR Phase II 1988 National Aeronautics and Space Administration
  10. "HIGH PERFORMANCE INDIUM GALLIUM ARSENIDE ARRAYS FOR THE 1.0-1.7 MICRON SPECTRUM"

    SBC: Eti Instrument Systems Inc.            Topic: N/A
